To all 'whom it may concern. ""Be it known that I, WALTER EICHELKRAUT a subject of the King of Prussia, and resident of 6/8 Seehofstrasse, Zehlendorf, nearv Berlin, Germany, architect, have invented certain new and useful Improvements in Safety Devices for Cash-Desks, of which the following is a specification.

This invention relates to apparatus for regulating and controlling the access of persons to cashiers windows and like payment apertures in banks, post-offices, theaters and similar public buildings and has for its object to provide an arrangement for preventing the public on the one hand and the cashier on the other hand from being robbed.

In order that the invention may be clearly understood reference is made to the accom-l panyings drawings which show, by way of example, various methods of carrying out my invention.

Figure 1 is a cross-section of one arrangement. Fig. 2 is a detail elevation of part of the arrangement shown in Fi 1. Fig. 3 is a detail view of a slight modiiication. Fig. 4 is a cross-section of an electrical arrangement. Fig. 5-is a partial elevation of the same.

In Fig. 1 of the drawings, 1 is the cash Window 1n ront of which is built a chamber 2 having a door 3 admitting thereto. In the edge ot the door is a recess 4 in which a bolt 5 can engage. This bolt is connected to a bell-crank lever 10 through bell-cranks 6 and 7 and rods 8 and 9, the bell-crank 10 carrying .preferably a` roller 11 whichl may pro'- ject into the path of the window which is slidable sidewise. The cash window has a strip 12 with an'inclined surface 13 on which the -roller 11 of the bell-crank lever 10 can run, so that when the cashwindow is moved in the direction of the arrow a the lever 10 is turned and thereby the bolt 5 caused to engage the recess 4 in the door and lock the latter through the medium of the bell cranks 6 and 7 and the connecting rods 8 and 9.

Now, in order only to be able to open the i rounding the rod 15 and secured at one end thereto and at the other end to the wall of the chamber 2, engages a recess 21 or the like in the cash Window. The cash window can thereforejonly be moved, if the rod 14 `is presed back by the closing of thedoor' and the bolt 20 withdrawn from the recess 21 by means of the levers 16 and 17 and the connectlng rods 15 and 18. At the same time las the cash window is moved, the bolt 5 engages with the recess 4 of the door in the manner already described and the door is thereby locked'. The unbolting of the door can only take place again ithe cash window is fully closed and the roller 11 enabled to take up the position again shown in Fig. l.

The bolting arrangement 14 to 21 of the cash window may -be dispensed with, if the arrangement shown at Fig. 3 is provided. In this case the bolt is engaged by means of a spring actuated latch 23 engaging a recess 22 in the same, so that the inclined surface of the strip 12 cannot move the roller 11 of the bell-crank and so that, the movement of the cash window is prevented. The withdrawal of the latch 23 takes place by means of the latch bolt of the door which presses against the latch 23 and thereby withdraws it from the recess 22 of the bolt 5 against the action of its spring. rlhe cash window can thus only be moved and the roller 11 moved outward and the bolt 5 caused to engage the recess 4 in the door, when the door is closed. h

In the construction shown 'at Figs 3 and 4 the locking takes place through electrical means. rlhe ylocking of the cash window 1 is effected by means of a bolt 24 which is movable within a solenoid 25 and brought into engagement with a recess or the like contact piece 29 on the closing of the door by means of the door latch against the action of the spring 32 and thereby completes the circuit. The solenoid is therefore excited and withdraws the bolt 24 out of the recess of the cash 'Window freeing the latter, so

that it can be opened. The bolt 5, which serves to bolt the door, is in this case arranged within a solenoid 33 and is. actuated by a spring 34 which tends to Withdraw the bolt from' the recess 4 of the door.- The solenoid is likewise arranged' in the circuit of a battery E and with a contact piece 35, opposite which is positioned a spring contact 36 connected with the other end of the solenoid 33. As soon as the cashwindow is moved from its closed position, the inclined surface 13 of the strip l2 contacts with the spring contact 36, so'that the latter is pressed into contact with the contact piece 33 and .the circuit of the-solenoid33 completed, so -as to draw the bolt 5 into the recess 4 when the door is bolted, IWhen'the window is again closed, the spring contact 26 is re-l leased and the circuit ,of the solenoid 33 broken. V'llhe bolt within the solenoid 33 7 is therefore withdrawn from the recess/4 of the door by means of its spring 34, so that the door can then be opened. l/Vhen the door is opened, the bolt 30 is drawn out of contact with the contact piece29 by meansof its spring 32 and thecir'cuit of the solenoid 25 broken, so that the s ring 26 of the bolt 24 thereby presses the y olt into the recess 27 of the cash windowl and locks the latter. It is well evident that the constructions may be readily variedwithout departing from the essential-.feature ot the invention. For example tlpexlocking arrangement may be eected by pneumatic or hydraulic means.

I claim f 1. An apparatus for regulating and controlling the access of persons to cash desks, comprising, in combination, a chamber in front of the cash desk, a door admitting to .said chamber, a window'for the cash desk, and an interlocking arrangement between said door and window whereby the window can only be opened when the door is closed and whereby the door can only be opened when the window is closed. a.y

2. An apparatus forregulating and con; trolling the access of persons to cash desks, comprising, inv combination, a chamber in front of the cash desk, a `door admitting to said chamber, a window for the cashdesk, a bolt ada tedto lock the window when the latter is c osed, a bolt adapted toV lock .the door when the latter is4 closed, means for loperating the window bolt from the door to lock the Window on the openinF of the door and to release the window .on the closing of the door, and means for operating the door bolt from the window to 'lock the door on l the window is opened.,

Locales the opening of lthe window. and to release the door on the closing of the window.

' 3. An apparatus for regulating and controlling the access of persons to cash desks, comprising, in combination, a chamber in front of the cash desk, a door admitting to said chamber, a window for the cash desk, a bolt adapted to lock the window when the latter is closed, a bolt adapted to lock the door when the latter is closed, means for operating the window bolt from the dor to lock the window on the opening of the door and to release the window on the closing of thedoor, and means for operating the door bolt from the window to lock the door on the opening of the window and to release the door on the closing ofthe window and means for holding the door bolt withdrawn until the door is closed, so as to lock window in its closed position until the door is closed.

4. An apparatus for regulating and controlling the access of persons to cash desks, comprising, in combination, a chamber in front of the cash desk, a door admitting to said chamber, a window for the cash desk,

` a bolt for the door, a bolt for the window and electrical connect-ions whereby the Window bolt is operated to release the window .when the door Iis closed, and whereby the door bolt is operated to lock the door when v5. An apparatus forregulating and con v trolling the access of persons to cash desks,

comprising, in combination, a chamber in y front of the cash desk, a door admitting to said chamber, a window" for the cash desk, a door bolt normally held withdrawn under -the action of a spring, a Solenoid surround ing thedoor bolt, an electric battery in circuit with the solenoid, contacts adapted to complete the circuit through said solenoid von the opening of the Window so as to operate the door bolt and lock the door, a winf dow bolt normally held in locking position under the action of a spring, a solenoid surrounding the Window bolt and in circuit with the battery, and contacts adapted to complete the circuit through the solenoid' of the window bolt on the closin of the door so as to Withdraw the window olt and release the window.

ln witness whereof l have hereunto set my hand in the presence of two witnesses.
